hi, i tried to simplify my code as much as possible and extract exactly where my problem is occuring, so the code below if copied and pasted wil compile, i have just included the neccessary pieces from multiple files where i have found a problem,
the problem, i set my window as a desktop_mode, then i draw a 2dpanel at the bottom of the viewport that overlays the 3d viewport, if the mouse cursor is over the black 'drag-line' and left mouse is held down, the panel can be resized/dragged up and down,
there could be a problem in my code, but from tests i am guessing something else, if i load the program up and without resizing i try to drag the panel, it misses the mark by about 20px, as soon as i resize by any amount it behaves as it should, the code shouldn't be wrong as i have used it before, but i might be wrong,please check for me,you can just copy paste code....
sorry if it is a bit long but i have tried to preserve exactly how i use it,not usually in one file though
